FUMIGATING COMPOSITION.

T 0 all whom it may] concern Be it known that I, FERDINAND SIGNORET, acitizen of France, residing at 8 Place de la Bourse, Marseille, in the Republic of France, have invented new and useful Ime provements in Fumigating Compositions, of which the following is a specification.

Sulfurous acid is the gas mainly employed for fumigating or sterilizing casks, wine vats, etc. It .is also largely used for other disinfecting purposes. this gas, sulfur Wicks may be burnt, composed of canvas, paper or other'substance forming a skeleton which is then coated with sulfur. These wicks of various forms have the disadvantage of allowing drops of fused sulfur to drop into the casks 0r vats,

&c. Various disadvantages result from this:

For instance, the sulfur spread on the strips of canvas, paper or other substance, loses a considerable percentage of its bulk by melting and running, and this molten sulfur is extinguished in contact with'the damp part of the cask or with the liquid, in the case of a vat which is being emptied. Hence it is impossible to use the entire mass and when the ignited drop meets the liquid or the damp Wood, sulfureted hydrogen may be formed which then communicates to the whole receptacle its characteristic and nauseating odor.

The object of the present invention is an improved composition which avoids all these disadvantages, and has the property of burning in its entirety, without fused sul-' fur running. This result is obtained by manufacturing it in the following way:-v Sulfur in grains or in coarse powder is mixed with ordinary silicate of soda and this mixture is dried after' it has been molded or pressed into slabs which have been divided into tablets' In order to make these tablets grind 100 kilograms of sulfur in order to conform it into grains of about 3 millimeters. Pour the coarse powder thus obtained into 35 liters of silicated soda; or of commercial potash, which mixture is then stirred in order to obtain an intimate mixture in the form of paste. This paste is transformed under a roller into the form of slabs 8 millimeters thick, which are passed under polishing rollers coatedwith flowers of sulfur to powder the same and thus prevent adhesion. The slabs are passed afterward under a winged roller that divides the Specification of Letters Patent.

In order to produce slab into tablets by tracing the longitudinal division, the transverse division and the grooves and perforations in the respective tablets being formed by passing the slabs through another machine for this purpose- These grooves permit the subsequent breaking of the slabs into separate tablets. One may, if desired, obtain the tablets by means of a simple press. The tablets thus obtained are'then dried in any convenient manner and will be rendered thereby very homogeneous and rigid. Each tablet will Weigh about Patented Nov. 2, 191 5.

100 grams and is divided into a number of parts. v

In the accompanying drawings :Figure l is a plan view of a slab of brimstone after it has been molded; Fig. 2 is a section on the line 1-1 of Fig. 1. I

This tablet is divided into'twenty parts A bymeans ofgrooves C and then each of these parts is again divided intotwo by grooves D. Each of these parts is perforated with a hole B, to enable it to be suspended in the cask by a wire, an incommanufacture of a fumigating product con-. sistlng in mixing comminuted sulfur in the form of grains of approximately 3. millimeters in diameter With a solution of soluble silicate of an alkali metal to coat the grains, in drying this mixture, and then in molding the substance to a convenient form.

2. A fumigating product in the form of an intimate mixture of sulfur in the form of grains of substantially 3 millimeters in diameter, and silicate of an alkali metal.

In testimony whereof I have signedmy name to this specification in the presence of two subscribing witnesses.
